Multilevel cascaded photovoltaic (PV) inverters can create interleaved voltage waveforms, allowing for reduced filter sizes and higher efficiencies, whilst still allowing for the maximum power point tracking (MPPT) of individual PV modules. However, unlike the micro inverter, a high gain boost converter is not required due to the series nature of the PV modules. To reduce wiring and installation costs...
Field-weakening in interior PM machines is performed by using negative rf-axis current to oppose the magnet flux and hence reduce the total fundamental rf-axis flux at high speeds. Due to the rotor saliency, the rf-axis current produces large amplitude harmonic airgap flux density components which can cause large harmonic stator iron losses. Reducing the magnet flux density reduces the required rf-axis...
